[0067] "Presenter" Transmitters, Nodes, Extenders, Receivers, Daisy-Chained Large and Small AV Systems
[0068] The present invention proposes an expandable device for switching and distributing digital audio-visual signals and its operation method, and describes its components, system architecture and system operation method. Multiple transmitters (Tx) and receivers ( Rx) and optional nodes to achieve the functions of traditional equipment, such as interfaces, switchers, splitters, matrix switchers and signal resolution converters, forming a scalable and easy-to-install digital audio-visual signal switching and distribution device. In order to distinguish them from traditional Tx and Rx, these new Tx and Rx will be called "demonstrator" Tx and "demonstrator" Rx in this article.
[0069] Please refer to figure 1 and figure 2 , figure 1 It is Embodiment 1 of the prior art system, figure 2 It is Embodiment 1 of the present invention. The system architecture 200 of the pre...

Abstract
The invention provides systems, devices, methods and software to daisy chain multiple individual transmitters, optionally nodes, optionally extenders, and receivers to form any sized scalable system of digital video and audio signal switching and distribution. The video audio systems are for a simpler system design, wiring, control and expansion, to accomplish signal interfacing, switching, splitting for many varied input and output requirements with a scalable pair of transmitters and receivers.
Description
[0001] This application claims priority to US Preparatory Patent Application No. 61 / 492,546, filed June 2, 2011, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a complete system of devices, methods, and system control software, providing a series of multiple transmitters, receivers, nodes, extenders, or bidirectional duplexers in a daisy chain form to achieve digital video and audio switching and distribution without the need for a central switcher or splitter or matrix switcher. The invention includes transmitters, receivers, nodes, duplexers, control devices, extenders, cables, software and systems. Background technique [0003] At present, buildings such as companies, governments, educational institutions, or residences all have two types of electronic systems, such as network and audio-visual systems. There are obvious differences between the two, such as: the network system can process information, t...
